The Big Bang Cosmology is explored, looking at its observational successes in explaining the expansion of the Universe, the existence and properties of the cosmic microwave background, and the origin of light elements in the universe. Properties of the very early Universe are also covered, including the motivation for a rapid period of expansion known as cosmological inflation. The third edition brings this established undergraduate textbook up-to-date with the rapidly evolving observational situation. This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader's understanding and learning. Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology.

    Richard Carrier, world renowned philosopher and historian, explains the four reasons he does not accept the Christian religion, describing four facts of the world that, had they been different, he would believe. He is brief, clear, and down to earth, covering the whole topic in under ninety pages of easy-to-read explanation. Those four reasons are God's silence, God's inaction, the lack of evidence, and the way the universe looks exactly like a godless universe would, and not at all like a Christian universe would, even down to its very structure. Dr. Carrier addresses all the usual replies to these claims, in ways you might not have heard before, relying on his wide experience in debating and studying these issues all over the world for more than fifteen years. A perfect book to introduce yourself, or your friends, to why fewer educated people are embracing Christianity than ever before. Ideal for handing out to door-to-door missionaries.

    However, once their predictions were compared to the results of experiments in the real world, it became clear that the principles of classical physics and mechanics were far from capable of explaining phenomena on the atomic scale. With this realization came the advent of quantum physics, one of the most important intellectual movements in human history. Today, quantum physics is everywhere: it explains how our computers work, how lasers transmit information across the Internet, and allows scientists to predict accurately the behavior of nearly every particle in nature. Its application continues to be fundamental in the investigation of the most expansive questions related to our world and the universe.However, while the field and principles of quantum physics are known to have nearly limitless applications, the fundamental reasons why this is the case are far less understood. In Quantum Physics: What Everyone Needs to Know, quantum physicist Michael G. Raymer distills the basic principles of such an abstract field, and addresses the many ways quantum physics is a key factor in today's science and beyond. The book tackles questions as broad as the meaning of quantum entanglement and as specific and timely as why governments worldwide are spending billions of dollars developing quantum technology research. Raymer's list of topics is diverse, and showcases the sheer range of questions and ideas in which quantum physics is involved. From applications like data encryption and quantum computing to principles and concepts like "quantum nonlocality" and Heisenberg's uncertainty principle, Quantum Physics: What Everyone Needs to Know is a wide-reaching introduction to a nearly ubiquitous scientific topic.

    You experience it passing every day when you watch clocks tick, bread toast, and children grow. But most physicists see things differently, from Newton to Einstein to today’s quantum theorists. For them, time isn’t real. You may think you experience time passing, but they say it’s just an illusion.Lee Smolin, author of the controversial bestseller The Trouble with Physics, argues this limited notion of time is holding physics back. It’s time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics.What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilties. There are few ideas that, like our notion of time, shape our thinking about literally everything, with major implications for physics and beyond—from climate change to the economic crisis. Smolin explains in lively and lucid prose how the true nature of time impacts our world.

    Simon Critchley skilfully probes some of the most perennial but least understood aspects of humour, such as our tendency to laugh at animals and our bodies, why we mock death with comedy and why we think it's funny when people act like machines. He also looks at the darker side of humour, as rife in sexism and racism and argues that it is important for reminding us of people we would rather not be.

    

    As they see matters, wealth in the form of means of production and wealth in the form of consumers’ goods are essentially indistinguishable. For all practical purposes, they have no awareness of the existence of capital and of its importance. Thus, capitalists are generally depicted as fat men, whose girth allegedly signifies an excessive consumption of food and of wealth in general, while their alleged victims, the wage earners, are typically depicted as substantially underweight, allegedly signifying their inability to consume, thanks to the allegedly starvation wages paid by the capitalists.The truth is that in a capitalist economic system, the wealth of the capitalists is not only overwhelmingly in the form of means of production, such as factory buildings, machinery, farms, mines, stores, warehouses, and means of transportation and communication, but all of this wealth is employed in producing for the market, where its benefit is made available to everyone in the economic system who is able to afford to buy its products.Consider. Whoever can afford to buy an automobile benefits from the existence of the automobile factory and its equipment where that car was made. He also benefits from the existence of all the other automobile factories, whose existence and competition served to reduce the price he had to pay for his automobile. He benefits from the existence of the steel mill that provided the steel for his car, and from the iron mine that provided the iron ore needed for the production of that steel, and, of course, from the existence of all the other steel mills and iron mines whose existence and competition served to hold down the prices of the steel and iron ore that contributed to the production of his car.And, thanks to the great magnitude of wealth employed as capital, the demand for labor, of which capital is the foundation, is great enough and thus wages are high enough that virtually everyone is able to afford to a substantial degree most of the products of the economic system. For the capital of the capitalists is the foundation both of the supply of products that everyone buys and of the demand for the labor that all wage earners sell. More capital—a greater amount of wealth in the possession of the capitalists—means a both a larger and better supply of products for wage earners to buy and a greater demand for the labor that wage earners sell. Everyone, wage earners and capitalists alike, benefits from the wealth of the capitalists, because, as I say, that wealth is the foundation of the supply of the products that everyone buys and of the demand for the labor that all wage earners sell. More capital in the hands of the capitalists always means a more abundant, better quality of goods and services offered for sale and a larger demand for labor. The further effect is lower prices and higher wages, and thus a higher standard of living for wage earners.Furthermore, the combination of the profit motive and competition operates continually to improve the products offered in the market and the efficiency with which they are produced, thus steadily further improving the standard of living of everyone.In the alleged conflict between the so-called 99 percent and the so-called 1 percent, the program of the 99 percent is to seize as far as possible the wealth of the 1 percent and consume it. To the extent that it is enacted, the effect of this program can only be to impoverish everyone, and the 99 percent to a far greater extent than the 1 percent. To the extent that the 1 percent loses its mansions, luxury cars, and champagne and caviar, 99 times as many people lose their houses, run-of-the mill cars, and steak and hamburger.

    From questions that we all wrestle with in private to questions that you never thought to ask, Ask a Philosopher will get you thinking.

    Here, Robert Solomon and Kathleen Higgins tell the story of philosophy's development with great clarity and refreshing wit. The authors begin with the most ancient religious beliefs of the east and west and bring us right up to the feminist and multicultural philosophies of the present. Along the way, they highlight major philosophers, from Plato and the Buddha to William James and Simone de Beauvoir, and explore major categories, from metaphysics and ethics to politics and logic. The book is enlivened as well by telling anecdotes and sparkling quotations. Among many memorable observations, we're treated to Thomas Hobbes' assessment that life is nasty, brutish, and short and Hegel's description of Napoleon as world history on horseback. Engaging, comprehensive, and delightfully written, A Passion for Wisdom is a splendid introduction to an intellectual tradition that reaches back over three thousand years.

    A full fledged techie himself, he relates some classic philosophical reflections, his interviews with dozens of fellow techies, and his own personal take on his Catholic beliefs to provide, like a set of "worked out sample problems," the hard data on the challenges and joys of embracing a life of faith as a techie. And he also gives a roadmap of the traps that can befall an unwary techie believer. With lively prose and wry humor, Brother Guy shows how he not only believes in God but gives religion an honored place alongside science in his life. This book offers an engaging look at how--and why--scientists and those with technological leanings can hold profound, "unprovable" religious beliefs while working in highly empirical fields. Through his own experience and interviews with other scientists and engineers who profess faith, Brother Guy explores how religious beliefs and practices make sense to those who are deeply rooted in the world of technology.

    

    In this book, the American pragmatist Richard Rorty and the French analytic philosopher Pascal Engel present their radically different perspectives on truth and its correspondence to reality.Rorty doubts that the notion of truth can be of any practical use and points to the preconceptions that lie behind truth in both the intellectual and social spheres. Engel prefers a realist conception, defending the relevance and value of truth as a norm of belief and inquiry in both science and the public domain. Rorty finds more danger in using the notion of truth than in getting rid of it. Engel thinks it is important to hold on to the idea that truth is an accurate representation of reality.In Rorty's view, epistemology is an artificial construct meant to restore a function to philosophy usurped by the success of empirical science. Epistemology and ontology are false problems, and with their demise goes the Cartesian dualism of subject and object and the ancient problematic of appearance and reality. Conventional "philosophical problems," Rorty asserts, are just symptoms of the professionalism that has disfigured the discipline since the time of Kant. Engel, however, is by no means as complacent as Rorty in heralding the "end of truth," and he wages a fierce campaign against the "veriphobes" who deny its value.What's the Use of Truth? is a rare opportunity to experience each side of this impassioned debate clearly and concisely. It is a subject that has profound implications not only for philosophical inquiry but also for the future study of all aspects of our culture.
